Surface Treatment

Electroplating is a process used to change the surface properties of a metal part by adding a metal coating onto its surface through the action of electric current. The metal part to be coated is first immersed into a salt solution that contains the metal to be deposited. The metallic ions of the salt solution carry a positive charge and are attracted to the metal part which carries a negative charge.
Non-electrolytic coating involves the application of corrosion resistant materials, lubricants, and other functional materials to the surface of the objects to improve their corrosion resistance, wear resistance, and for decorative functions.
